A buffer overflow vulnerability has been found in XAMPP affecting version 8.2.4 and earlier. An attacker could execute arbitrary code through a long file debug argument that controls the Structured Exception Handler (SEH).

XAMPP through 5.6.8 and previous allows SQL injection via the cds-fpdf.php jahr parameter. NOTE: This product is discontinued.

An issue was discovered in XAMPP before 7.2.29, 7.3.x before 7.3.16 , and 7.4.x before 7.4.4 on Windows. An unprivileged user can change a .exe configuration in xampp-contol.ini for all users (including admins) to enable arbitrary command execution.

Xampp for Windows v8.1.4 and below was discovered to contain insecure permissions for its install directory, allowing attackers to execute arbitrary code via overwriting binaries located in the directory.

A vulnerability was found in XAMPP 7.1.1-0-VC14. It has been classified as problematic. Affected is an unknown function of the component Installer. The manipulation leads to privilege escalation. It is possible to launch the attack remotely.

XAMPP installs multiple packages with insecure default passwords, which makes it easier for remote attackers to obtain access via (1) the "lampp" default password for the "nobody" account within the included ProFTPD installation, (2) a blank default password for the "root" account within the included MySQL installation, (3) a blank default password for the "pma" account within the phpMyAdmin installation, and possibly other unspecified passwords. NOTE: this was originally reported as a problem in DFLabs PTK, but this issue affects any product that is installed within the XAMPP environment, and should not be viewed as a vulnerability within that product. NOTE: DFLabs states that PTK is intended for use in a laboratory with "no contact from / to internet."

Cross-site request forgery (CSRF) vulnerability in security/xamppsecurity.php in XAMPP 1.6.8 allows remote attackers to hijack the authentication of users for requests that change a certain .htaccess password via the xampppasswd parameter.

The installer in XAMPP through 8.1.12 allows local users to write to the C:\xampp directory. Common use cases execute files under C:\xampp with administrative privileges.

XAMPP through 5.6.8 allows XSS via the cds-fpdf.php interpret or titel parameter. NOTE: This product is discontinued.

iart.php in XAMPP 1.7.0 has XSS, a related issue to CVE-2008-3569.

security/xamppsecurity.php in XAMPP 1.6.8 performs an extract operation on the SERVER superglobal array, which allows remote attackers to spoof critical variables, as demonstrated by setting the REMOTEADDR variable to 127.0.0.1.

Multiple unquoted Windows search path vulnerabilities in Apache Friends XAMPP 1.5.2 might allow local users to gain privileges via a malicious program file in %SYSTEMDRIVE%, which is run when XAMPP attempts to execute (1) FileZillaServer.exe, (2) mysqld-nt.exe, (3) Perl.exe, or (4) xamppcontrol.exe with an unquoted "Program Files" pathname.

XAMPP 1.8.1 does not properly restrict access to xampp/lang.php, which allows remote attackers to modify xampp/lang.tmp and execute cross-site scripting (XSS) attacks via the WriteIntoLocalDisk method.
